“It just blows your mind what you see. I mean every day it’s something different. But the one thing I got out of this was the compassion of the people who witnessed it,” MBTA Police Sgt. Preston Horton said. “We have our ‘See Something, Say Something’ campaign thinking of terrorism, but this time it was a small animal being abused.”

The dog, named “Dolce,” was turned over to animal control and was checked out by a veterinarian for any injuries.

“She’s doing really well. Her physical came out to be pretty good,” Dr. Marvelyn Motamed of Boston Animal Control said. “Usually after any type of trauma, the first 48 hours are the most important. So far she seems to be doing well.”
